INTERNAL-OOMIBUSTION-ENGINE CASING.

Specification of Letters Patent. 7

Patented Mar. 7, 1916.

To all whom it may concern:

Be it known that I, GEORGE T. HANCHETT, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Internal Combustion-Engine Casings, of which the following is a full and clear specification.

My invention relates to internal combustion engines and more especially to a casing inclosing the operating parts.

The object of my invention is to provide a simple and cheaply constructed casing by reason of which the amount of metal cast ing is reduced, the engine made lighter and cheaper and the parts more readily accessible to inspection and overhauling.

An example of the invention is illustrated in the accompanying drawing in which- Figure 1 is an end view of the engine with the end of the casing removed, and Fig. 2 is a side view thereof, with the side of the casing removed.

Referring more specifically to the drawings, 10 indicates the cylinders, 11 the water jacket, 12 and 13 the water supply and return pipes, 14 the fuel inlet chamber and 15 the main fuel supply passage. Valves 16 under the control of springs 17 and cams 18 operate to control the intake of fuel in the respective cylinders, the details of this construction not being shown in the present case, as it forms no part of the invention herein claimed. The connecting rods 19 are suitably connected with the crank shaft 20, provided with the oil scoop 21 which takes up oil from the troughs 22 in a pan 23.

From the construction shown, it will be 7 apparent that the operative parts of the engine, such as the valves, cams and crank shaft are not inclosed within the usual main casting, the cam shaft being journaled in brackets 24, secured to base plate 25 at the projecting lug or block 26, which is integral with the main cylinder casting. The lugs 26, form one of the connections of the engine with its support and to them the casing to be described is secured.

The casing comprises the upper tubular shell 27 secured to the lugs or blocks 26 and inclosing the valve mechanism and a portion of the cam shaft and connecting rods. The lower section of the casing is in the form of a cup-shaped shell 28, which telescopes over the lower end of tubular shell 27, and may be secured thereto as by bolts 29. The cup shaped shell 28 has mounted in it the oil pan 23, above referred to. It will be understood that this oil pan is merely a detail of illustration and not necessary to my invention in its broader sense, which resides in the more general arrangement of. the casing. I prefer to secure the cup-- shaped casing 28 upon the outside of the tubular shell 27 so as to prevent the drip of lubricating oil thrown out by the rotation of the crank shaft and other inclosed members from finding its way to the outside of the casing. i

The casing herein shown is of sheet metal construction, which I prefer to employ. It

will be understood that in practice the cas-.

ing will preferably be fitted with suitable doors or other means of ready communication with the parts to be adjusted, such as a the valve mechanism, and that these doors are not herein shown as not being essential to the broad features claimed.

I claim: I

1. Apparatus of the character described, comprising in combination a cylinder casting, a crank shaft, a crank shaft bearing supported by said cylinder casting, and a casing formed of an upper tubular shell inclosing the cylinder casting and the upper I over the lower portion of said tubular shell and secured thereto for inclosing the lower portion of the crank shaft.
